问题描述

我已经找堆栈/文档一些教程/其他问题，但还是无法弄明白。唉！

发出API请求和解析出（要分配给变量，但是这是一个奖金这个问题），这就是我想要。为什么我不能列出的项目的标题和链接？

 ＃！的/ usr / bin中/蟒蛇对于替补＃刮板屏

更新：

这工作，感谢您的帮助，并指出我的错字

 项目= root.findall（'项目/项目）
在项目的项目：
     打印item.find（标题）文本
     打印item.find（链接）。文本


解决方案

 项目= root.findall（项目）

应

 项目= root.findall（'项目/项目）

I've look for some tutorials/other questions on stack/documentation and still can't figure it out. ugh!!!

Making the API request and the parsing out (want to assign to variables but that's a bonus to this question), This is what I'm trying. Why can't I list the title and link for the items?

#!/usr/bin/python

# Screen Scraper for Subs
import urllib
from xml.etree import ElementTree as ET

show = 'heroes'
season = '4'
language = 'en'
limit = '1'

requestURL = 'http://api.allsubs.org/index.php?' \
           + 'search=' + show \
           + '+season+' + season \
           + '&language=' + language \
           + '&limit=' + limit

root = ET.parse(urllib.urlopen(requestURL)).getroot()
print root
print '\n'

items = root.findall('items')
for item in items: 
     item.find('title').text # should print: <![CDATA[Heroes Season 4 Subtitles]]>
     item.find('link').text # Should print: http://www.allsubs.org/subs-download/heroes+season+4/1223435/

UPDATE:

This worked, thanks for the help and pointing out my typo

items = root.findall('items/item')
for item in items: 
     print item.find('title').text
     print item.find('link').text

解决方案 

items = root.findall('items')

should be

items = root.findall('items/item')
